Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set halo engagement ring foundation in 18K white gold offers a low-profile setting designed for everyday grace and durability.

Crafted with precision in Williamsburg, the band’s smooth comfort fit ensures it rests gently against the skin, while the halo mount prepares to amplify the center stone’s brilliance without overwhelming the hand. The 12 x 6 mm marquise shape lends an elegant elongation, balancing architectural sharpness with a refined sparkle.

Each piece reflects a commitment to ethical sourcing, featuring a lab-grown diamond option that reduces environmental impact while maintaining exceptional clarity and fire. The white gold’s polished finish is inspected meticulously to meet standards of lasting wearability.

Ideal for those seeking a ring that pairs well with stacking bands or stands confidently alone, this design suits slender to medium finger sizes and slips comfortably beneath gloves or sleeves thanks to its restrained profile.

Resizing is available to ensure a precise fit, and our Brooklyn studio welcomes you to explore custom options or complete your ring with a center stone chosen to your taste and lifestyle.
